Specification of Letters Patent.

Application filed March 12, 1921. Serial No. 451,904.

To all whom it may concern:

Be it known that I, ANTHONY MaTRAzzo, a subject of the King of Italy, residing at Baltimore, in the State of Maryland, have invented new and useful Improvements in Polishing Devices, of which the following is a specification.

This invention relates to devices for tools especially designed for use in finishing highly polished surfaces, such as automobiles or other vehicles, furniture and the like, the device being susceptible 'of use for polishing objects of any character.

Another object is the provision of a tool operated polishing device whose use will materially reduce the time and labor of finishing polished surfaces; and to regulate the amount of pressure, in the work, so as to avoid liability of using excessive pressure durin the rubbing or olishing operation and thus guard against injury to the finish.

Another object is the provision of a device of the above character which, with minor changes may be used for scrubbing or sand papering and smoothing various surfaces.

lVith the above and other objects in View, the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claims.

In the drawings Figure 1 is a vertical longitudinal sectional View of a polishing or rubbing device constructed in accordance with the invention.

Figure 2 is a top plan view with the cover plate removed.

Referring in detail to the drawings, wherein like characters of reference denote correspondin parts, the reference character 10 indicates t e body of the device which is preferably rectangular in plan and is of hollow construction. The body is provided with a cover plate 11, which is secured to the body proper by means of fastening devices 12 which pass through apertured flanges 13 extending from above the body to the cover plate. Secured to the cover plate is a handle or grip 14, by means of which the device is held while in use.

The device further includes a movable polishing unit 15, which is secured to the body 10 and is movable relatively thereto. This unit is formed of inner and outer walls 16 and 17, the former being preferably formed of metal or similar non-yieldable material, while the wall 17 is formed of leather or other flexible material and is'secured to the wall 16 as shown at 18. The walls 16 and 17 are yieldingly held in separated relation by means of coiled springs 19 whose opposite ends engage these walls. The flexible wall 17 is preferably covered with felt or other suitable polishing material 20 so as to provide proper frictional engagement with the surface bein polished.

The polishing unit 15 is slidingly connected to the body 10 and for this purpose the said body hasextending longitudinally of its opposlte side walls guide flanges 21, while the inner wall 16 of the polishing unit carries spaced channeled members 22 which receive the guide flanges 21 and hold the polishing unit in sliding engagement with the body of the device. Mounted between ears 23 extending from each of the end walls of the body 10 are anti-friction rollers 24 which bear upon the inner wall 16 of the polishing unit and serve to reduce friction during the operation of the device.

For the purpose of imparting a sliding movement to the polishing unit, the body 10 has rotatably mounted therein a transversely arranged crank shaft 25, the latter bein mounted in bearings 26 arranged upon eac side of the body 10 and having a connection with the polishing unit 15 through the medium of a pitman. The shaft 25 may be connected to a flexible shaft 27, which may receive power from any suitable source for example, an electric motor (not shownl.

The device is susceptible of various changes, such as substituting a suitable abrasive material for the felt cover 20, whereupon the device may be used as a sandpapering or smoothing device, or a covering of a difl'erent character substituted for the felt 20, so that the device may be used for scrubbing or similar work. The right is therefore reserved to make such changes as properly fall within the scope of the appended claim.

Having described the invention what is claimed is A device of the class described comprising a hollow body, acover plate removably secured to said body, a handle secured to said cover plate, guide flanges extending from the side walls of said body, a polishing unit including a. casing having an inner nonyieieleble Well and an outer yieldable well and compressible elements separating the wells, spaced channeled members carried by the non-yieldeble wall of the polishing unit end engaging said guide flanges, ears extending from OEPPOSIEGV ends of said body, anti-friction r01 ers carried by said ears and engaging the non-yieideble well of said poiishin unit, a crenk shaft jeurneied in suit- 10 able eerin in said. body, means for connecting sei shaft to the nen-yieldable wall of the polishing'unit and means for rotating said shaft.

In testimony whereof I it? ANTHONY MA'JIRAZZU.
